The clinical value of tumor burden at diagnosis in Hodgkin lymphoma
2004
BACKGROUND The authors investigated the clinical role of tumor burden (TB) in patients with Hodgkin lymphoma, relating this parameter to most of the current clinical and prognostic factors and to the best predictive multifactorial models. METHODS The volume of TB at diagnosis was measured directly from the initial staging computed tomography scans in 351 patients who were treated on standard protocols. The mean patient age was 34.0 years ± 16.4 years. Forty-six patients had clinical Stage I disease, 201 patients had Stage II disease, 64 patients had Stage III disease, and 40 patients had Stage IV disease. There were 146 symptomatic patients. Overall survival (OS), disease-free survival (DFS…
Left ventricular mass in hypertensive patients with mild-to-moderate reduction of renal function
2010
Aim: Left ventricular hypertrophy (LVH) is an independent predictor of cardiovascular (CV) morbidity and mortality. The aim of the present study was to evaluate the relationship between LV mass and mild-to-moderate renal dysfunction in a group of non-diabetic hypertensives, free of CV diseases, participating in the Renal Dysfunction in Hypertension (REDHY) study. Methods: Patients with diabetes, a body mass index (BMI) of more than 35 kg/m 2 , secondary hypertension, CV diseases and a glomerular filtration rate (GFR) of less than 30 mL/min per 1.73 m 2 were excluded. The final sample included 455 patients, who underwent echocardiographic examination and ambulatory blood pressure monitoring.…
Left ventricular diastolic filling alterations in subjects with mitral valve prolapse: A Doppler echocardiographic study
1993
To assess left ventricular diastolic filling in mitral valve prolapse (MVP), we studied 22 patients with idiopathic MVP and 22 healthy controls matched for sex, age, body surface area and heart rate. A two-dimensional, M-mode and Doppler echocardiographic examination was performed to exclude any cardiac abnormalities. The two groups had similar diastolic and systolic left ventricular volumes, left ventricle mass and ejection fraction. Doppler measurements of mitral inflow were: E and A areas (the components of the total flow velocity-time integral in the early passive period of ventricular filling, E; and the late active period of atrial emptying, A), the peak E and A velocities (cm.s-1), a…
Endogenous 3-methylhistidine excretion in healthy women and men with reference to muscle protein metabolism.
1984
Presently 3-methylhistidine excretion is widely used for monitoring the metabolic status of patients during different kinds of clinical conditions. Aim of the study was to reconsider its predicative value on the basis of a larger collective of healthy persons and to find a standardization independent from sex. Therefore endogenous 3-methylhistidine release of 40 healthy adults (24 women and 16 men) was measured and related to body weight, body surface area, arm muscle circumference, and nitrogen and creatinine excretion. A positive correlation could be observed only for 3-methylhistidine and creatinine excretion and that to the same extent both for females and males. Assuming that the excre…
An observational study to evaluate the long-term outcomes of treatment with etanercept in patients with plaque-type psoriasis
2015
Background There is an unmet need for long-term, real-life data on the effect of a drug-free interval between treatment cycles in patients with plaque psoriasis being treated with etanercept, which is licensed for intermittent and continuous treatment. Objective The aim of this study was to determine the average duration of the drug-free interval between etanercept treatment cycles in patients with plaque psoriasis. Methods This was a non-interventional, open-label, multicentre, prospective study in patients for whom the decision had already been made to initiate treatment with etanercept during routine practice in German centres. Clinical outcomes were documented over 36 months with study …
Relationship between aortic root size and glomerular filtration rate in hypertensive patients
2016
OBJECTIVE: Recent studies suggest that enlarged aortic root diameter (ARD) may predict cardiovascular events in absence of aneurysmatic alterations. Little is known about the influence of renal function on ARD. Our study was aimed to assess the relationships between glomerular filtration rate (GFR) and ARD in hypertensive subjects. METHODS: We enrolled 611 hypertensive individuals (mean age: 52 ± 15 years; men 63%). ARD was measured by echocardiography at the level of Valsalva's sinuses using M-mode tracings. It was considered as absolute measure, normalized to body surface area (ARD/BSA) and indexed to height (ARD/H). GFR was estimated by the Chronic Kidney Disease Epidemiology Collaborati…
Prevalence and predictors of left ventricular hypertrophy in patients with hypertension and normal electrocardiogram.
2013
Background: Electrocardiography (ECG) has low sensitivity for detecting left ventricular hypertrophy (LVH), while echocardiography cannot be routinely performed. Design/methods: In this study we evaluate the prevalence of LVH and diastolic dysfunction in hypertensive patients with normal ECG. We excluded patients with cardiovascular (CV) diseases, diabetes, chronic kidney disease, or presenting ECG-LVH or other ECG anomalies. The enrolled 440 hypertensive patients underwent echocardiographic examination (Acuson Sequoia 512); LV mass was indexed by body surface area (LVMI) and LVH was defined as LVMI >125 g/m2 in men and >110 g/m2 in women. Diastolic function was evaluated by mitral inflow a…

Influence of metabolic syndrome on hypertension-related target organ damage. J Intern Med 2005; 257: 503-513. Objectives. The aim of our study was to analyse, in a wide group of essential hypertensive patients without diabetes mellitus, the influence of metabolic syndrome (MS) (defined according to the criteria laid down in the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults) on markers of preclinical cardiac, renal and retinal damage. Design. Cros…
Estimation of pulmonary arterial pressure by measuring the size of the right pulmonary artery in the suprasternal echocardiogram.
1982
We studied 175 patients within 24 hr before cardiac catheterization with suprasternal echocardiography to evaluate whether pulmonary arterial hypertension can be derived by measuring the size of the right pulmonary artery. Group I consisted of 103 patients without pulmonary arterial hypertension (enddiastolic less than or equal to 12 mm Hg; mean pressure less than 20 mm Hg) and group II consisted of 72 patients with pulmonary arterial hypertension. The right pulmonary artery could be imaged in 91.2% of the patients studied. The size of the right pulmonary artery at the end of diastole in group I measured 17.9 +/- 0.2 mm (mean +/- SEM) and correlated best to the body surface area in this gro…
Efficacy and tolerability of multiple-dose SDZ IMM 125 in patients with severe psoriasis.
2006
Although cyclosporin is effective in immunosuppression following organ transplantation and in the treatment of psoriasis, its use is limited by its side-effects, notably impaired renal function and hypertension. As SDZ IMM 125, a new derivative of the cyclosporin family, showed considerable immunosuppressive activity in experimental studies, with less effect on renal function, it was considered a potential successor to cyclosporin for both indications. In this multicentre, double-blind, placebo-controlled study, the efficacy and tolerability of 40, 100, 200 and 400 mg SDZ IMM 125 daily were studied in 59 patients with psoriasis. Patients were followed for a period of 5 weeks (4 weeks treatm…
